| Abstract: | Cucumber is the main vegetable product in China and there exists positive meaning in science and technology contribution rate to cucumber outputs, On the basis of definition and methods about science and technology progress contribution rate, the method of frontier production function and technique efficiency analysis were chosen in the thesis. The contribution rate of hard technology progress, soft technology progress and the essence factor inputs of the main cities and provinces in China were calculated respectively through the cost and profit samples of land for cucumber production and the statistic analysis software SPSS was applied to estimate the parameters and calculate the contribution rate. The conclusion was that at average level, the science and technology progress especially the soft technology progress had positive effect on the cucumber production; there existed obvious discrepancy and unbalance in the dry land cucumber production; five different kinds of areas can he distinguished according to the results. |
